Final answer:
The unit price of beef can be calculated by dividing the total cost by the number of pounds of beef. In this case, the unit price of beef is $0.49 per pound.
Step-by-step explanation:
The unit price of beef can be calculated by dividing the total cost by the number of pounds of beef. In this case, we need to find the unit price of beef based on the given graph. To do this, we can choose two points on the graph and divide the difference in the total cost by the difference in the number of pounds.
Let's choose two points on the graph: (0.66, 1) and (3.62, 7). The difference in the total cost is 3.62 - 0.66 = $2.96, and the difference in the number of pounds is 7 - 1 = 6 pounds.
To find the unit price, we divide the difference in the total cost by the difference in the number of pounds. So, the unit price of beef is $2.96 / 6 pounds = $0.49 per pound.
